Broadband satellite with dual frequency conversion and bandwidth aggregation
First Claim
1. A satellite, comprisinga payload subsystem comprising a first frequency converter, a second frequency converter, a satellite feeder link antenna feed, and a satellite user link antenna feed, said payload subsystem being communicatively coupled (i) to at least one gateway by a feeder link operating at a first frequency band;
- and (ii) to a plurality of user terminals by a user link operating at a second frequency band, wherein;
the first frequency converter downconverts, to a third frequency band, as an aggregated block, signals received at the satellite feeder link antenna feed from the gateway via the feeder link, said third frequency band being substantially lower than the first frequency band and the second frequency band;
the downconverted signals are processed by the payload subsystem and routed to the second frequency converter; and
the second frequency converter upconverts the downconverted signals to the second frequency band for transmission by the satellite user link antenna feed over the user link to the user terminals;
the first frequency converter is proximate to the satellite feeder link antenna feed array;
the second frequency converter is proximate to the satellite user link antenna feed array; and
the received signals are aggregated within a user beam feed cluster and the aggregated received signals are routed, at the third frequency band, from a location proximate to the satellite user link antenna feed array to a location proximate to the satellite feeder link antenna feed array.

Abstract
A broadband satellite having a payload subsystem configured to provide dual frequency conversion and bandwidth aggregation is communicatively coupled (i) to at least one gateway by a feeder link operating at a first frequency band; and (ii) to a plurality of user terminals by user links operating at a second frequency band. The payload subsystem has a first and a second frequency converter a satellite feeder link antenna feed, and a satellite user link antenna feed. The first frequency converter down converts, to a third frequency band, as an aggregated block, signals received at the satellite feeder link antenna feed from the gateway via the feeder link. The third frequency band is substantially lower than both the first and second frequency band. The down converted signals are routed to the second frequency converter for up converting to the second frequency band for transmission over the user link to the user terminals.
